Generally, tooth whitening is not painful, but some patients experience sensitivity. The procedure itself usually doesn't hurt, but many report discomfort or pain after the treatment. This sensitivity is often temporary and mild to moderate, described as a burning sensation.
Understanding Tooth Whitening Sensitivity
Several sources indicate that post-whitening sensitivity is common. This is because the hydrogen peroxide used in whitening treatments penetrates the tooth enamel, potentially exposing the nerves in the dentine. This source states that the treatment itself is painless, while this article notes that patients with sensitive teeth may experience discomfort during or after treatment.
The sensitivity is often felt in the first 24-48 hours after the procedure, as noted in [one source](Reference not linked directly, but the text is pulled from the provided reference). Another source confirms that pain after whitening is common, ranging in intensity.
- Temporary Sensitivity: Most reported sensitivity is temporary and manageable with over-the-counter pain relievers like ibuprofen or acetaminophen, as suggested in this article.
- Severity Varies: The intensity of discomfort varies greatly depending on the individual and the whitening method used. Some people experience no pain at all, while others might have significant sensitivity. One Reddit thread even mentions a user describing the process as "a bit painful", though they compared it to less severe procedures.
Managing Sensitivity
Several strategies can help manage post-whitening sensitivity:
- Using desensitizing toothpaste
- Avoiding acidic or very hot/cold foods and drinks
- Following your dentist's post-treatment instructions
While some may experience mild discomfort, tooth whitening itself is generally not a painful procedure. The potential for temporary sensitivity should be considered, but it is often manageable with simple remedies.
